400GBASE-SR8 QSFP-DD PAM4 850nm 100m DOM MTP/MPO MMF Optical Transceiver Module
400G QSFP-DD SR8 module supports multimode fiber (MMF) link lengths of up to 100m via MTP/MPO-16 connectors. It supports eight electrical interface channels that operate in 50G PAM4 coding mode to produce 400G (8x50G) data rates. It is compliant with the IEEE 802.3bs protocol and the 400GAUI-8/CEI-56G-VSR-PAM4 standard. The multiplexing and demultiplexing of eight wavelengths are managed within the device and connect 400G signals from the server side (NIC) to the data center aggregation switch.
